Usage

Doubt and doubtful may be followed by a subordinate clause beginning with that, whether, or if: I doubt that (or whether or if ) the story is true. It is doubtful that (or whether or if ) the story is true. There is some doubt that (or whether or if ) the story is true. In negative or interrogative sentences, that almost always introduces the subordinate clause: I do not doubt that the story is true. Is it doubtful that the story is true? Is there any doubt that the story is true? The expressions doubt but and doubt but that occur in all varieties of standard speech and writing: I don't doubt but she is sincere. There is no doubt but that the charges will affect his career. Doubt but what occurs mainly in informal speech and writing: There is no doubt but what the rainy weather will hurt the crops.

Where a clause follows doubt in a positive sentence, it was formerly considered correct to use whether ( I doubt whether he will come ), but now if and that are also acceptable. In negative statements, doubt is followed by that: I do not doubt that he is telling the truth. In such sentences, but ( I do not doubt but that he is telling the truth ) is redundant

The -b- first appears between 1420–30 in imitation of Latin dubit-
